Aggregated Results

This gives you the unfiltered MapSwipe results aggregated on the task level. This is most suited if you want to apply some custom data processing with the MapSwipe data, e.g. select only specific tasks. If you want geometries on each task instead of a geom column, see Aggregated Results (with Geometry).

Schema

One row per task, with the following columns:

Name Type Description
idx integer Sequential row index.
task_id string The ID of the task. For tile-based project types (e.g. Find Features) this is a composition of TileZ-TileX-TileY.
0_count integer The number of users who marked this task as 0, e.g. “no building” for Find Features.
1_count integer The number of users who marked this task as 1, e.g. “building” for Find Features.
2_count integer The number of users who marked this task as 2, e.g. “maybe” for Find Features.
3_count integer The number of users who marked this task as 3, e.g. “bad imagery” for Find Features.
total_count integer The total number of users who mapped this task.
0_share float 0_count divided by total_count. This gives you the share of all users who marked as 0.
1_share float 1_count divided by total_count. This gives you the share of all users who marked as 1.
2_share float 2_count divided by total_count. This gives you the share of all users who marked as 2.
3_share float 3_count divided by total_count. This gives you the share of all users who marked as 3.
agreement float Scott’s Pi inter-rater reliability. 1.0 means all users agreed; lower values indicate disagreement. Empty when only one user has mapped the task.
quadkey string Bing Maps quadkey identifying the tile (tile-based project types only).
project_internal_id integer The internal numeric project ID.
group_internal_id integer The internal numeric group ID for the group this task belongs to.
task_internal_id integer The internal numeric task ID.
geom string The geometry of this task as WKT (MULTIPOLYGON, EPSG:4326).
tile_z integer Tile zoom level (tile-based project types only).
tile_x integer Tile X index (tile-based project types only).
tile_y integer Tile Y index (tile-based project types only).
url string URL to the satellite imagery tile shown to users (tile-based project types only).

Additionally, project type specific data can be found here. E.g. Validate projects which were created based on OSM data, will have data describing the original OSM object included.

Sample download

A 10-row preview is shipped alongside these docs for reference. It is not the live dataset — for the full export, see the MapSwipe data page. The live file is delivered as gzipped CSV (.csv.gz) — unzip before use; the sample below is already decompressed.
